Frequently asked questions
Which is the largest employer in Manufacture of chemicals and chemical products in Liège province?
Among companies, Prayon, with 1,082.8 full-time equivalents reported (financial year 2025).

Not necessarily: headcount is reported by the company for all its sites, and the company is ranked by the address of its registered office. 39 out of 66 companies in the sector report employees there.
Why does this ranking differ from other lists?
